[BUG] TOC on the right not visualised properly when too long

[nessn2]

Describe the bug

When there are enough titles to reach the bottom of the page, the table of content is simply cut off and becomes practically unusable.

Expected behavior

I guess it could be implemented so when the TOC is very long you can scroll it up and down?

Build Environment

• OS: MX Linux (Debian)
• Theme version/commit: v0.1.1, ece2351
